Chichester’s Pills, a patent medicine which were manufactured from 1881 into the 1950s, were branded as a “Relief for Ladies,” promising to alleviate “functional derangements of the female organism” – in other words, menstrual pain. Originally, the pills were called “Chichester’s Pennyroyal Pills.” This name was later changed when the herb pennyroyal was found to be toxic, although it is unknown whether the original pills contained the herb. Chichester’s Pills became the center of a federal campaign for truth in advertising, which culminated in the 1920 libel lawsuit “Chichester Chemical Co. vs. The United States.” Following the lawsuit, Chichester’s changed their packaging, and the pills were presented as more of an herbal supplement than a cure-all medicine.
